Turning now to FIG. 1, each of cords comprises a first end coupled with the loop strap formed on one of the corners and a second end being secured on the surface, wherein the multi-purpose shelter 100 further comprises a plurality of pegs, wherein each of the pegs is coupled with the second end of each one of the cords to secure each one of the cords at an angle respect to the surface.

With specific reference to FIGS. 1-2, the middle pocket 140 may bisect the covering 110 into two equal area sections. The first rod member 120 may be loosely received within the middle pocket 140, wherein the forward end 121 and the backward end 122 may be concavely extended at an acute angle with the surface. In this embodiment, each of the angles formed by the cords respect to the surface may be equal or different, and the acute angles formed by each of the forward end 121 and the backward end 122 of the first rod member 120 with the surface may be equal or different. Preferably, the angles formed by each of the cords are equal and each of the acute angels formed by each of the forward end 121 and the backward end 122 are equal. Preferably, each of the angles formed by each of the cords is smaller than each of the acute angles formed by each of the forward end 121 and the backward end 122 of the first rod member 120.
